SOME recent interesting experiments on theeffects of different colored light on thegrowth of plants and on the colors and shapesof their leaves, flowers, and fruit, are de-scribed by a contributor to Der Stein derWeisen (Vienna, February 27). We translateand abstract below a large part of the article : All the rays that come from the sun passthrough space in the form of ether-waves ofgreat speed, which vary in intensity and char-acteristics. These ether-vibrations that pro-duce the sensation of red when they strike our eyes are theslowest, and the ether-waves that correspond to them are longerthan those that correspond to violet, altho, for example, theether-waves of red make 3f)5,ooo,ooo,ooo vibrations in a second,yet this enormous number is increased in the case of the violet
